How do i change the water height for the water here that's a part of the rivers?

Just type height in the search bar

@Mopuit Have you notice that you cannot change river’s water height in the same way as the ocean?

Sadly, but it seems that you can’t edit river/water levels.

Looks like you need to just remove all water…

You can remove rivers and keep water only in one level, but it’s a bit hard to do. Need to:

  • Remove Water entity.
  • Add some spawner (triggers could be used) that will respawn Water entity.
  • Edit Water entity in entities.blk. Set water__level that you want to see and e.t.c.
